1.Stainless Steel Flanged Hex Head Screws:Made from 18-8 stainless steel, these screws have good chemical resistance and may be mildly magnetic. The flange distributes pressure where the screw meets the surface, eliminating the need for a separate washer. Head height includes the flange. Length is measured from under the flange.

Inch screws meet ASTM F593 material quality standards and IFI 111 dimensional standards.

Metric screws meet DIN 6921 dimensional standards.

2.Stainless Steel Flanged Hex Head Screws with Slotted Drive:Install these screws with a wrench or a screwdriver. The flange distributes pressure where the screw meets the surface, eliminating the need for a separate washer. Dimensions meet ASME B18.6.3 specifications. Head height includes the flange. Length is measured from under the flange.

18-8 stainless steel screws have good chemical resistance and may be mildly magnetic. 316 stainless steel screws are more corrosion resistant than 18-8 stainless steel screws and have excellent resistance to chemicals and salt water. They may be mildly magnetic.

Match the thread spacing of mating components. Coarse threads are the industry standard; choose these screws if you don’t know the threads per inch. Fine threads are closely spaced to prevent loosening from vibration.

3.Extreme-Strength Stainless Steel Flanged Hex Head Screws:For strength comparable to that of Grade 9 steel and the corrosion resistance of stainless steel, choose these screws. They are work-hardened for extreme strength and can be used in heavy duty stamping applications as well as earth-moving machinery, such as bulldozers and excavators. The flange distributes pressure where the screw meets the surface, eliminating the need for a separate washer. Head height includes the flange. Length is measured from under the flange.

18-8 stainless steel screws have good chemical resistance and may be mildly magnetic. 450 stainless steel screws are more corrosion resistant than 18-8 stainless steel screws and have good resistance to chemicals and salt water. They are magnetic.

4.18-8 Stainless Steel Serrated-Flange Hex Head Screws:Made from 18-8 stainless steel, these screws have good chemical resistance and may be mildly magnetic. Serrations under the head grip the material surface for mild vibration resistance, and the flange distributes pressure where the screw meets the surface, eliminating the need for a separate washer. Head height includes the flange. Length is measured from under the flange.

Match the thread spacing of mating components. Coarse threads are the industry standard; choose these screws if you don’t know the threads per inch. Fine threads are closely spaced to prevent loosening from vibration.

5.Super-Corrosion-Resistant 316 Stainless Steel Serrated-Flange Hex Head Screws:More corrosion resistant than 18-8 stainless steel screws, these 316 stainless steel screws have excellent resistance to chemicals and salt water. Serrations under the head grip the material surface for mild vibration resistance, and the flange distributes pressure where the screw meets the surface, eliminating the need for a separate washer. Screws may be mildly magnetic. Head height includes the flange. Length is measured from under the flange.

Stainless Steel Flanged Hex Head Screws are used for critical, high assembly accuracy requirements, as well as to withstand significant shock, vibration, or alternating load occasions. C-grade bolts are used because the surface is relatively rough, and the assembly accuracy requirements of the occasion are low. Threads on the bolt, generally coarse threads, are common threads; West Asia common thread bolts self-locking is better, mainly used for thin-walled parts or to withstand shock, vibration, or alternating loads. General bolts are made of part of the thread; Stainless Steel Flanged Hex Head Screws are mainly used for the nominal length of the shorter bolts as well as the requirement of more extended thread occasions. The bolts with holes are used for occasions that require bolt locking. Stainless Steel Flanged Hex Head Screws can accurately fix the mutual position of the connected parts and can withstand the shear and extrusion generated by the lateral force.

The head of Stainless Steel Flanged Hex Head Screws consists of two parts, the hexagonal head and flange, and the ratio of its "support area to the stress area" is more significant than that of ordinary hexagonal head screws so that these screws can withstand higher preload. The anti-loosening performance is better, and thus, they are widely used in automobile engines, heavy machinery, and other applications and used in automobile engines, heavy machinery, and other products.

The characteristics of Stainless Steel Flanged Hex Head Screws include high tensile, compressive, torsional, and shear strengths, as well as suitable fastening and decorative properties. 

The design and material of Stainless Steel Flanged Hex Head Screws enable them to have the following distinctive features.

High Strength: Stainless Steel Flanged Hex Head Screws can withstand high tensile, compressive, torsional, and shear strengths, which makes them suitable for use in A variety of occasions requiring high-strength connections excel. Carbon steel flange is a better choice because it can provide a vital support area and stress area ratio, withstand higher preload, and improve relaxation performance. 

Good tightening performance: Compared with ordinary bolts, Stainless Steel Flanged Hex Head Screws have a larger support area to stress area ratio, which can provide higher preload force and prevent loosening. In addition, the flange can be designed with a flat bottom or a toothed shape according to the needs of the industry, and the latter is better for fastening. 

Decorative features: Stainless Steel Flanged Hex Head Screws have a smaller head with holes and slots that lock more securely with slight deformation. This design enhances the fastening effect and has good decorative properties, which are suitable for products with high anti-corrosion requirements and surface finish requirements for the occasion. 

Easy to install and maintain: The connection of Stainless Steel Flanged Hex Head Screws belongs to the fastener connection, which is easy to install and dismantle and convenient for maintenance. This design can increase the pre-tensioning force to prevent loosening and will not cause a phase change in the material composition of the connection. 

Material Diversity: Stainless Steel Flanged Hex Head Screws are usually made of stainless steel, such as Stainless Steel 201, Stainless Steel 304, Stainless Steel 316, and so on. Different materials can be selected depending on the application requirements and cost considerations. 

In summary, Stainless Steel Flanged Hex Head Screws, because of their high strength, good fastening performance, decorative performance, and ease of install and maintenance in a variety of occasions that require high-strength connections and aesthetic decoration in the Because of its high strength, good fastening performance, decorative properties, and easy installation and maintenance, it is widely used in various occasions that require high strength connection and beautiful decoration.
